Livestream: Watch Elon Musk at IAC2017 as he reveals Mars plan
Here’s how you can watch a livestream of Elon Musk at IAC2017
After many months of teasers from Elon Musk and SpaceX, Musk is about to give a presentation on SpaceX’s updated Big Falcon Rocket, which is expected to one day bring humans to Mars and potentially even support a city-sized colony on the planet.
Musk’s 2016 presentation on the Interplanetary Transport System captured the imaginations of many people, kindling the sort of excitement he has always hoped to inspire. Sitting in the audience during his Guadalajara, Mexico talk, his esoteric desire to make people excited to get out of bed in the morning resonated with me.
Updated: Elon Musk teases SpaceX-built cities on the Moon and Mars
Nevertheless, we now find ourselves almost exactly one year after his 2016 talk, and many things are believed to have changed with both SpaceX’s interplanetary colonization strategy and the hardware the company expects to develop to accomplish that colonization. Musk has said that tonight’s presentation will focus on the how of SpaceX’s Mars colonization efforts, entailing a somewhat smaller booster and spaceship with “major improvements”, as well as some “unexpected applications” for the vehicle.
Major improvements & some unexpected applications to be unveiled on Friday at @IAC2017 in Australia

What exactly those unexpected applications might be is fittingly unclear, if they are indeed less than obvious. More obvious applications for a fully-reusable heavy launch vehicle include
- More affordable access to orbit
- Mass launches of satellite constellations
- Off-the-shelf access to the surface of the Moon
- Space tourism in Earth orbit
- Cheaper and simpler space stations in a single launch
- Direct and rapid access to the Outer Solar System for more complex planetary exploration missions
These are just a handful of the potential uses and benefits that could be derived from a fully-reusable heavy launch vehicle like the Big Falcon Rocket (BFR). Unexpected or not, the near-Earth utility of a theoretical BFR is undeniable.

Aside from additional information on those unexpected applications, we can expect several exciting tidbits. Musk has teased new and improved videos of their Raptor rocket engine conducting live-fire tests, and we also have reason to believe that his talk will be accompanied by an equally slick and thrilling collection of renders of the updated BFR in action. Mirroring last year’s rather shocking unveiling of physical hardware development in the form of Raptor’s first test fire and a massive carbon fiber propellant tank, I personally expect to see confirmation of still more tangible hardware development.
A growing amount of recent news pointing to Boca Chica, Texas as the first launch site for SpaceX’s massive new rocket may also lead to an official statement from Musk himself either confirming or denying this, maybe accompanied by a tentative schedule for pad development. Regardless of what is revealed, tonight’s presentation is bound to be yet another exceptional opportunity to hear Musk wax poetic about SpaceX’s desire to make humanity a multiplanetary species.

Tesla Semi factory is getting a celebration nobody expected
Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.
Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.
While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.
Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.
The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.

Elon Musk just set a condition that could end Falcon 9 as we know it
Elon Musk says SpaceX will finally retire Falcon 9 once Starship flies reliably every week.
Elon Musk gave the clearest timeline yet for retiring Falcon 9, SpaceX’s workhorse rocket.
The comment came in a reply on X, where Musk wrote that “once Starship is flying reliably several times per week, it makes sense to shift super scarce SpaceX engineering and production resources to Starship to get launch rate to several times per day, which means winding down Falcon.” He was responding to physicist Casey Handmer, who noted that NASA is reportedly uneasy about SpaceX phasing out Falcon after building what Handmer called the most successful launcher ever, with the fleet nearing 1,000 total launches.
Now @SciGuySpace reports NASA is in a tizzy because after running the most successful launcher ever for more than a decade and nearing 1000 launches, @SpaceX is planning to retire Falcon in favor of Starship in a few years.
Sorry, NASA, you’ve had 15 years to burn down the… https://t.co/uCNoMwK0v9
— Casey Handmer (@CJHandmer) August 22, 2026
Falcon 9 is still SpaceX’s busiest vehicle by far. The company is on pace for roughly 140 to 145 Falcon flights this year, following 165 in 2025, president Gwynne Shotwell told Time earlier in 2026. She has already said Falcon flights would “tail off” as Starship comes online, while reports indicate that SpaceX has stopped booking new Falcon 9 launches past 2028 and halted production of some expendable Falcon hardware, according to Bloomberg.
It’s worth noting that Musk’s post is a condition, and not a countdown on when Falcon will retire. Starship has not yet flown weekly, let alone daily. Its most recent flight in July ended with a soft splashdown in the Indian Ocean, a milestone Musk pointed to earlier this month when he said the vehicle’s heat shield problem was effectively solved. SpaceX towed that ship to Christmas Island for inspection, and the next flight, Flight 14, is aimed at putting Starship into orbit for the first time. A tower catch attempt for the upper stage has been pushed back to what Musk has called “a few months” away.
SpaceX and a new Trump order that could rewrite the next decade of launches
The gap between Falcon’s role today and Starship’s promised role tomorrow matters most to NASA. Falcon and its Dragon capsule remain the only way the agency rotates astronauts to and from the International Space Station, and Starship is not certified to carry NASA crews. Musk’s post did not address how that handoff would work if Falcon winds down before a crew-rated Starship variant exists. The timing lines up with Musk’s other recent Starship comments. Two days before the Falcon post, he told a different X user that SpaceX is aiming for more than 30 Starship launches a day by 2030, or roughly 10,000 a year, a figure tied to the Trump administration’s new push for higher national launch cadence. Falcon, which took over a decade to reach its first 100 launches, was never built to approach that kind of volume.
For now, Falcon 9 keeps flying at a near-record pace while Starship works to prove it can do the job Musk has already picked out for it.
Tesla Cybercab is set to launch in Austin, Texas, on September 3, as the company has officially started sending out invitations to a dedicated event it will hold in the city where its headquarters is located.
The Cybercab is Tesla’s dedicated ride-sharing vehicle: it features just two seats and has no steering wheel or pedals. It is aimed at fully autonomous passenger transport, and will operate in the Robotaxi fleet alongside the Tesla Model Y, which has been performing driverless rides for real-world passengers for more than a year.
Thank you so much @Tesla for inviting us to the Cybercab launch in Austin! 🤠 pic.twitter.com/F1rAR8zd5O

The launch of the Cybercab marks the next chapter in Tesla’s autonomy story. The company has been developing autonomous transport for years with its Full Self-Driving (Supervised) platform, which is available in any vehicle the company has built with the proper hardware and software capabilities.
Its capabilities vary by hardware and software version, but Tesla says its latest hardware version, known as AI4, can deliver full autonomy. However, future vehicles will operate with even more robust hardware packages, as Tesla will develop AI4.5 and AI5 for even more capability in its vehicles.
Following a report from The Information that surfaced earlier this week, the writing was on the wall that Tesla was set to launch Cybercab in the near term. The report stated Tesla could launch Cybercab as soon as the end of August. Tesla came close and has booked it for September 3.
The big thing with this event being scheduled is not necessarily that Tesla is launching a new vehicle, but instead that it is launching a vehicle that has no steering wheel or pedals and will operate exclusively on a self-driving program that is evidently nearing full autonomy. If the event allows vehicles to take passengers on public roads and drop them off wherever they please within the City of Austin, it will be a drastic advancement in the company’s self-driving story.
People have ridden in Cybercab previously: Tesla had the “We, Robot” event in October 2024, which allowed people to experience fully autonomous rides in a closed circuit at Warner Bros. Studios in Burbank.

Additionally, Tesla launched employee rides in Cybercab in July.
It’s a drastic step forward for Tesla, whose CEO, Elon Musk, has promised for years that the company would release a fully autonomous vehicle and platform capable of allowing drivers to relinquish any responsibility behind the wheel.
